I’m going to tell you the names of my favorite breakfast foods. We could even put a period after the word “foods,” couldn’t we? In fact, we did. © Capital Community College The Colon: a sentence gateway We know, however, what’s going to come after this period. I’m going to tell you the names of my favorite breakfast foods. That’s right, a LIST of breakfast foods. © Capital Community College The Colon: a sentence gateway I’m going to tell you the names of my favorite breakfast foods: meuslix, cornflakes, oatmeal, grits and gravy, and yogurt on toast. And the proper punctuation mark to set off this list from what precedes it is a colon. The colon “announces” that a list is about to follow; it is the gateway to that list. © Capital Community College The Colon: a sentence gateway My favorite breakfast foods are meuslix, cornflakes, oatmeal, grits and gravy, and yogurt on toast.
